Very poor aftersales service
If you want good aftersales service for any issues or questions you may have don't buy from dn auto gas parts.
I bought some parts and I had a few questions about what I received. The website is not that descriptive but I thought I had ordered what I needed. When it arrive a part didn't fit another and one of the adapters fitted a gas bottle to which I thought it shouldn't.
I raised these issues the company by sending emails and pictures and videos. Whatever I tried they couldn't answer my question clearly. They are so involved with gas parts they couldn't communicate with some who know less than they did. They got frustrated with themselves and said I should send everything back. This is I did as I was fed up with the quality of service I was receiving. When they got the returned package they said a nut was missing and charged me for the whole part. They even sent a photo showing the missing part. I asked for the pieces I paid for back and the went silent. So I paid for something I never received.
I ordered directly from them. On ebay there are some similar reviews.
